shown clearly iniP 1 and uidotlower weights 4r* Cre arranged in therespective trougl'is to more the end pieces 1. Each lower or innermostend piece 1 rests against a frame The shook forming the sides 2 andbottomsl 3 is arranged horizontally with the Sides alternatingl with thebottoms, that` is to say, first is; a side, then comes shook for thebottom ot the box, then boards for two sides, then a bottom board and soon. Each bottom and sideniay consist of more than one piece ot board,tor example, the bottom 8 may consist ot two narrow boards which whenplaced side by side will` torni the bottoni of the box. rEhe bottoms andsides 2 are kept in vertical alinement between two vertical side plates(i suitably cured to the trame I of the machine and the lowermost board,either bottom or side, as the case may be, rests upon the upper bars ofthe'frames 5 heterereterred to. The slant of the troughs l is suilieientto cause the bote 'while the sides and bottoms also 'feed by gravitytast they are removed Jfrom underneath the pile.

Extending longitudinally and secured to the 'frames 5 are statioi'iaryrods 8 iornnng ways upon which a, carrier is slidably mounted. rThiscarrier con'iprises two blocks -it and iwhich areconnected by a rod 10on which is a sleeve 1l.. ln the upper end ot each block 9 is i'iiroteda pin 12 having a square head i3v in which is ro tatably mounted therear end ot" a sha'lt if-, (see Fig. 'l'he forward end oit each shaftlil: journalcd in a block 'l5 and each block 15 provided with a roller1G which is adapted to rido on a` rail 17, the rear end ot each rail 17beingr pivoted on a; rod 1S, as clearly shown in l `i;gs. 3, ft and rlierails 17 near the iront end are' coniiec'lcd by a strap 19', as shown in3 andl The two square heads t5 are. tied together by a strap S20, shownin Figs. 53 and 5. rlhus the track rails 17 may be swung up and down ona long; radins ot which the shaft 1S is the center, while the shat'ls 1twith Vtheir blocks 15 may also be swung up and dona pivoted at pins 12on a nnirh shorter radius. Projecting forwardly troni tach block l5 is arevoluble. shook supporting1 post 2l which is adapted to rotate with theshatt 1&1-, and each post 21 is prfwided with three studs 22, Q3 and Q4.the stads and 2.4; beine; in the saine plane ot rotation and stud 2?being somewhat hack thcreot' on account ot the tlitl'ere in widthbetween a bottom and a side en the carrier retracted the bars lie mieterthe lowermost shook. 'The op Q'xin ot the parte so timed that. if theice ot'shook is bottom piece 3 then each stud Q3 will lie edge ot thebottom piece 3 and as the earrier advances the studs will push thebottom piece 3 out from under the pack and carryv the bottom pieceforward as it rests upon the bars S21. When the bars 21 have carried thebottom piece to the proper point the bars are at the end of their strokeand they thendrop below the bottom piece and leave the saine restingupon two end pieces 1 which hare previously been placed in position in amanner to be described hereinafter. The. manner in which the carrier isactuated is as follows: A link :25 is pivoted at its upper end to. abracket 2li which -is secured to the bar 19, as shown in Fig, 5, and thelower end ot link Q5 is pivoted to an arm 27. as shown in Fig. 3 andFig, 17, which is loosely mounted on shaft Q8. rPhe forward end of thearin 27 is formed as a curved hook Qt, as shown in detail in Fig. 17,and iS provided with a roller 30 which is adapted to ride on a eain 3lits entering end having a roller 32 which strikes againsti roller BO inlifting; the lever 27. The cam 31 is cast on the sideo'f a gear mountedon shaft 34e which is mount-ed in a journal 35. A pitman tt) isconnected to the gear 33 at one end, and at the other end is connectedto an arm 37 pivoted at its lower end to a shaft 38. The upper end otthe arm 3T is provided with a slotted toi-k 39 which engages the sleeve1l on bar l0 so that as gear 33 rotates and arm 3T is rocked itreciproeates thc carrier. The cam 31 is so timed that when the carrierreaches the 'forward end ol' the stroke the lever 27 is allowed to dropwhich lowers the supporti og barsI 2l .trom under the shook and itremains` in this lower yposition while the carrier is being retracted bythe rearwardly swingrina` arm 37, and the carrier thus being loweredduring its return stroke causes the studs 23 to ride back freely underthe stack ot shook. During` the next torward stroke ot the. carrier asido must. be carried torward instead of a bottom as the bottom has instpreviously been cinried out as just desrribcd. and as the. side shook isnarrower than the bottom shook a stud 24 must be Vinorcd into position,which is a0- roinplished by i'iartially turning shafts 14.. On the rearend ot each shaft. 14. is a ratchet 4,() which is oiigaged by aretaining pawl 4l. At the forward end o'lf cach .shalt 14- is a ratchet'42 which is actuated by a spring pressed pawl 4?' .arried on anoscillating block Ll which is jonrnaled loosely on shaft lll andprovided with a` segmental gear A'l5 which meshes with a vertical rack413 rigidly mounted on the forward end of each carrier bloclij Si. Eachshaft 111 in moving down causes the segmental gear l5 to be rotated bythe stationary .rack 4G, which turns the ccillating block L14 in onedirection causing the pawl` to engage with a new tooth of the mincewilli ilie carrier'.

l find il' advisable to employ a pair of pins 158 in place otl a singlepin for tl'lereasoll that a single pin does not .give sllliicientnlovelllent to the level' 15G. Each time the lahle plate 9G is turned itnnlst be turned through onestllird of a revolution to present :l newlange at the top in ay horizontal position, and while the table 96 ismoving through one-third ot' a revolution the actuating mecha nisln justdescribed, rotates the Vclamp disk .124- one-fourth of a revolution.

During" a complete revolution of 'thetable and the clamp disks posiwillonly have heen moved twice as hut two sets of pins 158 are employed.This is for the riason that in making av inox one, side is first nailed.Then the boxY must he turned one-quarter of a eirele hy the Clamp dish124', and at the saine time the table titi must he turned onl7 one-thirdto permit the hox to rest on the next flange. This lirst` turning of theboX after the nailing of the first side is accomplis-hed hy the firstset ot' pins. while the tahle plate titi is moving' through its first.third of a reif'olution. The bottoni then haring heen nailed the tableplates 96 turn through their second third of a revolution ,and theseeondset of pins acting on lever '15G turns the Clamp disk 124 throughits second fourth of a revolution. The last side of the box having beennailed the table 96 then nieves through the. last, third of itsrevolution and during this last rnoren'tent the lever 15o is notactuated as itis not necessary to operate the damping; disk 124-, andthe latter is spread apart to release the eompleted hoxA and permit itto he ,.eted hy the ineoining end pieces whieh are to form a 'fresh hoX.
